am trying to make the Techlabs from Barracks/Factories/Starports not collide with units so that units dont get stuck in tight spaces.
when i made their Collide Index to 0, it didnt make a difference, furthermore click options to upgrade vanished when i did this.
when i tried to change the Footprint to an underground footprint, this worked beautifully and units could walk through them! BUT again the upgrade options vanished.
how would i make this work?
